Three types of radiation
There are 3 types of radiation, alpha (\(\alpha\)), beta (\(\beta\)) and gamma (\(\gamma\)). Their properties can be studied using an electrical field.
Alpha
\(\alpha\) - Slow moving positively charged particle, attracted to the negative plate.
Beta
\(\beta\) - Fast moving negatively charged particle, attracted to the positive plate.
Gamma
\(\gamma\) - Electromagnetic radiation (travels at the speed of light). No deflection.
